Abstract
Official abstract text for this publication.
Adhesive tape having at least two layers A and B laminated directly on one another, with at least one or both layers A or B being an adhesive, and the interfaces of the layers A and B laminated on one another being subjected to a physical method, the physical method being selected from the group consisting of corona discharge, dielectric barrier discharge, flame pretreatment and plasma treatment, before the layers are laminated to one another, with the two methods differing from one another.
First claim
Opening claim text (preview).
The invention claimed is: 1. An adhesive tape, comprising at least two layers A and B laminated directly to one another, at least one or both layers A or B being an adhesive, layer B being in the form of a foam, and the interfaces of the layers A and B that are laminated to one another being subjected to a physical method, the physical method being selected from the group consisting of corona discharge, dielectric barrier discharge, flame pretreatment and plasma treatment, before the layers are laminated to one another, and the treatment applied to one of said at least two layers differing from the treatment applied to the other. 2. The adhesive tape as claimed in claim 1 , wherein the interfaces laminated to one another possess an acid-base interaction or donor-acceptor interaction having been intensified or generated by the different types of physical treatments of the interfaces, one of which has been treated with an acidically modifying gas and the other having been treated with a basically modifying gas. 3. The adhesive tape as claimed in claim 1 , wherein the first physical treatment is a corona treatment in air and the second physical treatment is a corona treatment in N 2 , the O 2 content of the N 2 atmosphere being <1000 ppm. 4. The adhesive tape as claimed in claim 1 , wherein at least one of the layers A or B is viscoelastic. 5. The adhesive tape as claimed in claim 1 , wherein the adhesive is a pressure-sensitive adhesive. 6. The adhesive tape as claimed in claim 1 , wherein the layer B is an adhesive bonding component. 7. The adhesive tape as claimed in claim 1 , wherein the physical methods differed with respect to the dose which was applied to each of the interfaces. 8. The adhesive tape as claimed in claim 1 , wherein the treatment time for the interfaces of the layers A and B is different. 9. The adhesive tape as claimed in claim 1 , wherein the physical methods differed with respect to the process selected. 10. The adhesive tape as claimed in claim 1 , wherein in the case of the physical methods the following pure, or mixtures of, process gases form a treatment atmosphere: N 2 , O 2 , H 2 , CO 2 , Ar, He, ammonia, ethylene, optionally with steam or other volatile constituents being added. 11. The adhesive tape of claim 1 consisting of said two layers A and B laminated directly to one another.
